Logging for the Kiln Storage Service is automatically enabled and is called errors.txt. It is located in the directory containing your repositories which you specified during the installation process (by default: C:\KilnRepositories\errors.txt).

For Kiln versions 2.0 to 2.5 an additional logging option existed, which was enabled via the registry. You’ll be adding these keys at HKLM\Software\Fog Creek Software\Kiln\Daemon or HKLM\Software\WOW6432Node\Fog Creek Software\Kiln\Daemon if you’re 64-bit.

To enable, add a new String key named LogFile with a value of the path you want to logs to be stored in (e.g., C:\KilnRepositories\daemon.txt), then create a new String key named LogLevel with a value of info, critical, or debug depending on your needs.

Once you restart the Kiln Storage Service, logging will start. Log files don’t roll over, however, so beware of how large these files may get if left unchecked!
